Day of Defeat Source quickly replaces Counter Strike Source in the eyes of many.
User Rating: 8 | Day of Defeat: Source PC
Despite the game only having 4 maps at launch, almost every user-created map feels like it must have been made by Valve. The gameplay is very smooth, and can also require you and your team to co-ordinate your attacks if you don't want to all end up dead. MG's provide awesome firepower that can be quickly set up, helping push back the opposing players. Snipers, however, can quickly rid of this machinegun and put rushing back into the list of possibilities.
Weapons have larger recoil that Counter Strike, and crouching makes your grouping much smaller. This is a game that requires skill, as well as aim, and tactics.
All in all, this game makes you feel good inside.
